Hilux 4x4 Forum

can anyone give advice as to where my friend can take his v6 Fortuner for a decat? many people are interrested in doing it, but in our area no one seems to have done it before on a v6. we are in the Roodepoort/Randburg area.

Praat met Ralf Toyo Service Center (Ondekkers Weg naby die roadhouse). Hy sal jou kan help verseker,

thanks!

Cat...???
Het my Tuna ook een...???

Cat = Catalytic Converter...

Cat = Catalytic Convertor...

Yes

JR'S Exhausts Ontdekkers road newlands.
They did a very good job on my Hilux

Terrible echo in here....

Another question if I may...???

Why take it out...???

they say you can gain up to 7% with a de-cat. its like removing your tonsels..

catalytic converter = the most restrictive part of most exhaust systems = power loss = drop in fuel consumption

if SA can build coal fired power stations, then we dont needs cats either!!

enjoy!!

Remove it .... they just keep trying to drink our milk!!

Sal dit 'n verskil maak op my 3.0D4D?

Ek het die storie gehoor een keer by 'n vriend wat dit met sy Isuzu 3.0 Auto gedoen het en hy praat net goed van die conversion.

the removal of any restriction always results in improvements !!

Will your vehicle afterwards still stand up to the CO emission laws over there?

The removal of a catalytic converter ALWAYS improves performance!!! We have done
VW's
Merc's
Jeep
Ford
Audi
...........

There are a few ways

1. THE HACK
This involves the cutting of a small "window" in the cat, whether in place or removed, and hacking out the material with a hammer and long screwdriver. Then welding up the window.
Pro's: Cheap de-cat procedure, more power, cheaper than a cat replacement
Con's: Raspy exhaust note more resonance in the vehicle, extra heat through the cat shell can cause the floor to get warmer in that area

2. THE PIPE
This involves cutting out the cat completely and just fitting a straight pipe in its place. This is not always possible as on some vehicles the cat is part of the manifold. Typically non-turbo applications.
Pro's: Cheap de-cat procedure, more power, cheaper than a cat replacement
Con's: Raspy exhaust note more resonance in the vehicle

3. THE RESONATOR/SILENCER
This involves removing the cat and replacing it with a resonator type silencer that kills the exhausy resonance and absorbs a lot of heat. These usually start at about R1000 for supply and fitting at your local exhaust fitment centre.
Pro's: More power, quiet exhaust, no hot floor, cheaper than a cat repalcement
Con's: NONE

PLEASE NOTE: On all of the above; if your vehicle has an oxygen sensor before and after (pre and post) the catalytic converter you WILL need to have the vehicle re-chipped or a dummey O2 sensor (post) fitted as the engine management light will come on to show an emmisions fault. We have performed all of the above, the first two due to budget constraints on the clients part and are usually done as the cat is blocked.

We do not have emmisions monitoring as part of out roadworthy process so it will not affect anything in that regard. But if your vehicle is under warranty it WILL void your warranty. But it is the easiest horsepower gained on a modern vehicle.

So does my '06 3.0 D-4D have a cat?

Not sure on the 06 will do some research. My 05 2.5does note.

Thanks, appreciated

Ek het n roomer gehoor dat as jy jou voertuig verkoop nadat jy die cat verwyder het , en moet roadworthy , dan sal jy nie n roadworthy sertifikaat kry as jou voertuig as standaard met n cat uitgekom het nie.Dit gebeur seker nog nie maar dit is definitief in die pyplyn. Het iemand anders al daarvan gehoor ? ( Ek hoop dit is net n roomer )

There is talk of an annual roadworthy like they do in the UK which will include emmisions testing, but I don't see this happening for a long time to come. We still have to many old vehicles here that never had cats. The taxi industry drives this at the moment. The only requirements at this moment is that the exhaust must not leak, must be secure and not be noisy. So de-cat away. I would say that the legislation is at 3 years away from implementation and I would suspect it would only apply to vehicles from that date.

Ek het my cat so 2 jaar terug op my 2.7 uitgehaal nadat ek die 3de boks moes vervang in 2 jaar. Het n' freeflow opgesit en my bakkie trek van toe af soos n' bul.

To de-cat wont effect roadworthy. Its a case of if its fitted as an extra and not a standard SABS requirement, it must work. Cats are not gazzeted as a requirement. As for roadworhty every year, it has been in the pipeline since late 2004. Our infrastructure in sa wont handle it and with all the old cars etc. will take many many years to impliment. Lots of ducks for the gov. to get in a row in this regard before they can do anything anyway.

Ek weet dis `n baie ou draad die, maar ek het wyd en suid gesoek vir advies en raad oor de-cat.

Ek het die plunge gevat en my beast laat de-cat.
:o
Klink soos `n dier, maar tog geen effek binne kajuit.
Gaan egter wel 2 klein ekstra boksies laat insit waar hulle die laaste 2 cats verwyder het net om die effense resonansie te demper.

Supa Quick Menlyn doen die ding gereeld en het `n merkwaardige job gedoen. Dit vat net `n tydtjie, so be warned...

Ek sal oor so `n maand terugvoer gee oor die petrol verbruik

PS: Die V6 se exhaust het `n deel wat baie laag hang en jou ground clearance lelik beinvloed - hulle het daai stuk pyp ook mooi flush met die res van die exhaust laat sny

Wat was die prys by hulle?

Ek was R1350 armer maar dit het 2 dummy cats ingesluit - aparently nie nodig nie, maar ek het dit maar safe gespeel

en trek hy beter ?

JEEPIE wrote:en trek hy beter ?

Ek kannie regtig met eerlikheid sê nie siende dat hy alvorens klaar getrek het soos `n meneer. Hy voel meer responsive.

Just some information on the "mini-cats" I keep referring to:

They are installed where your O2 sensor goes. Then your O2 sensor, in turn, screws into the mini-cat.

The internal structure of the mini-cat actually contains the same inner as a catalytic converter in order to supply you O2 sensor with more or less the same exhaust gases it received before the catalytic converter inner was removed.

Apparently mini-cats are not necessary for 4l hiluxes before 2012, but I had them installed just to have piece of mind. I dont want to have engine lights and warnings coming on when I dont need them, especially on a trip.

Have a look at the pictures below that shows what they look like

Dankie Martin

Ek oorweeg om myne iewers in die volgende paar te laat doen.
Gelukkig is Supa Quick Menlyn nie te vêr van my af nie.

Doen julle self n guns en praat met Viper Performance in Kempton Park. Hulle werk is uitstekend!

Weet een van julle of my '04 2,7 dit in het? Ek het die "stage 1 conversion" by SAC gedurende 2008 laat doen en hulle het die uitlaat pyp verander asook die "chip" en die "airfilter" modifikasie. Hy trek reeds soos 'n 6 silinder of beter as sommige 6 silinders.....

Ek dink ek is in vir ten minste een boks want daar begin nou 'n resonasie voorkom as ek ry en as ek moet wil ek die CAT verwyder dieselfde tyd..

Het so 2 weke gelede my D4D hilux se cat uitgehaal en hy trek verseker beter en baie loop defnitief gladder.

Got my 4 cats removed last weekend, all I can say, WOW

TAU
Give some info price and place please.

Did mine @ noise boys in Germiston,

4 cats were removed & mini cats were fitted on the sensors in front of the 2 cats @ the back

Then 2 small "cowley" silencers were fitted to minimize the rattle inside the cabin,

Steel pipe from manufault to the big silencer @ the back was fitted

All for R5 k

Got a quote from Supa quick Menlyn for R1600. Cat removal and the fitting of mini cat dummy sensors on my 4.0l Hilux. Not bad at all.

where does one get these mini cats ?

Heh... I was also tempted to reply in that vein...
